SLlDlNGfDOOR' FASTENER.

SPECIFICATION forming part of Letters Patent No. 740,821, dated. October 6, 1903. Application filed January 14, 1903. Serial No. 139,028. (No modelil Improvements in Sliding-Door Fasteners; and.

v I do hereby declare the following to be a full,

clear, and exact description of. the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to means for securing sliding doors in closedposition, and has for its object'to provide an improved slidingdoor fastener of the class in which the 'releasing of the fastener and the sliding of the doorare accomplished by a single continuous movement of the fastener-handle.

W'ith this object in view the invention consists of improved attachments of this character, the construction, arrangement, and combination of the parts of which will be first fully described hereinafter and afterward specifically claimed.

I have illustrated an embodiment of myin vention in the accompanying drawings, in which- Figure l is a View in elevation, partly in section, of a fastener constructed in accord.

ance with my invention applied to double sliding doors, the doors being shown a slight distance apart and the fastener in position to engage the catch on the opposite door when closed. Fig. 2 is a view of a portion of a door in end elevation, partly in section, hav:

ing my improved fastener secured thereto.

Fig. 3 is a sectional detail view to be hereinafter referred to.

Like reference characters mark the same parts in all of the figures.

Referring specifically to the drawings, 1 1

mounted Within said brackets in position to normally and yieldingly hold the handlesin upright position, in which position the fastener, as hereinafter described, is in its normal locked position. 7

The fastener is indicated at 7, and consists of a bar curved to pass over the hub 2, pivoted at its inner end within the mortise and in the rear of the hub and provided with a hooked end projecting through a face-plate 18 on the edge of the door, the pivotal point" and hooked end being substantially in the same horizontal plane when the catch is in its locked position.

9 indicates a liftingbar mounted in the hub 2 to oneside of the bolt 4, the liftingbar being provided on its upper face with a curved notch to fitaroundthe pivot, whereby the turning of the pivot in the hub-will not be interfered with.

Where this fastener is to be used on a sin gle sliding door, the door-frame is provided with a striking-plate 8, having a suitable catch to engage the hooked end of the fastoner; but where the fastener is to be applied to double sliding doors the opposite door is provided with a handle on each side, a pivot, a hub, and a lifting-bar 9, as shown on the left of Fig. 1, the lifting-bar being normally in position under the hooked end of the fastener 7 when engaged with the catch of the striking-plate 8.

Should it be desired to lock the fastener so that it can only be opened from one side of the door, it is necessary that the handle and V For this purpose a locking-pin 11 is mounted in a bar in the lower-endof the handle, secured to a handle lug or button 12, having a pin 14: projecting from the opposite end thereof, the lockingpin 11 being normally held bya spring 15 in. a mortise or depression 13 in the hub 2, in

which position the pin 1e must rest in its bore or opening, as clearly shown in Fig. 3. This position is the normal position, and when the parts are so positioned, assuming the doors to be fastened together, the fastener on either door on either side thereof in being pulled away from the front edges of the door will first move slightly in the bracket 5 at its upper end, which movement will cause the hub 2 to turn, raise the fastener 7, and unlock locked and cannot be opened except upon the the door. If, however, the button or lug 12 is drawn outward, thus withdrawing the hub 16 of the locking-pin 11 from the mortise 13 of the hub and the pin 14 from its seat, the movement of the fastener-handle will simply turn the pivot 4 inthe hub and have no effect upon the fastener, so that when the hub 16 and pin 14: are thus withdrawn the doors are side from which the button or lug 12 projects, then only by reinserting the pin 14 and hub 16 in their seats. The handles when actuated will cause the fastener to be raised and unlock the doors. By turning the lug or button when withdrawn on the pin 11 as a center the pin 14 will restupon the surface of the handle and be retained in its withdrawn position.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described the combination of a hub journaled in an opening in the door, a latch pivoted in said opening, a pivot-bolt mounted in the hub, a handle secured to the bolt, a lifting-bar secured in the hub and projecting below the latch at its forward end, and means for locking said hub against rotation with respect to the handle as described.

2. In a device of the character described the combination with a rotatably-mounted hub, a pivoted latch, a handle pivoted in the hub, a lifting-bar carried by the hub, and

means for locking said hub against rotation with respect to the handle, substantially as described.

3. In a device of the character described the combination with a rotatably-mounted hub, of a pivoted latch, a lifting-bar carried by-the hub, a handle pivotally mounted in the hub, said hub having suitable recesses, a spring-impelled pin pivoted in the handle and normally in engagement with the recess of the hub, a button or lug carried by said pin on the outside of the handle, and a second pin secured upon the button or lug and adapted to engage in the recess in the handle when brought into register therewith, substantially as described.

4. Ina device of the character described the combination with abutting doors, of a hub rotatably mounted in each door, a han dle pivotally mounted in each hub, a latch pivoted in one door and projecting therefrom into. the opposite door when closed, a liftingbar attached to each hub in position to raise the latch when the handle is operated, and means for connecting the handle with, or disconnecting it from, the hub in one of the doors, substantially as described.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
